Vertical deflection

(重定向自Deflection of the vertical)
Earth's ellipsoid, geoid, and two types of vertical deflection
Erdschwerefeld: Lotrichtung, Geoid und Äquipotential

A : Geoid
B : Ellipsoid
C : Equipotential line
D : Astronomical zenith (plumb line)
E : Ellipsoidal zenith
F : Vertical deviation angle

The vertical deflection (deflection of the plumb line, astro-geodetic deflection) at a point on the earth is a measure of how far the direction of the local gravity field has been shifted by local anomalies such as nearby mountains. (Here "gravity" means apparent gravity—true gravity "reduced" by the earth's spin). They are widely used in geodesy, for surveying networks and for geophysical purposes.
